2. Understanding Your Readings
The Tanita BC-602 provides a comprehensive analysis of your body composition. Key measurements include:
- Weight: Your total body weight.
- Body Fat Percentage: The proportion of fat in your body.
- Muscle Mass: The total weight of muscle in your body.
- Visceral Fat Rating: An indicator of the fat surrounding your internal organs.
- Total Body Water Percentage: The amount of water in your body.
- Bone Mass: The estimated weight of your bone mineral content.
- Basal Metabolic Rate (BMR): The minimum calories your body needs at rest.
- Metabolic Age: Compares your BMR to the average BMR for your age group.
- Daily Calorie Intake (DCI): An estimate of the calories you need to maintain your current weight.
- Body Mass Index (BMI): A ratio of your weight to height.

3. Segmental Analysis
The unique segmental analysis feature provides individual readings for your trunk, left arm, right arm, left leg, and right leg. This allows you to monitor muscle mass and body fat distribution in specific body parts, helping to identify imbalances or track targeted progress.

Translated Usage Tips from Image:
- Measure once a week, at the same time of day.
- Place your scale on a firm and solid surface, not on a mat.
- Wait a moment after physical exercise before measuring, as physical activity may impact your body and cause inconsistency in results.
- Wait 2 to 3 hours after eating and avoid caffeine/alcohol for accurate weighing results.
- Stand barefoot on the scale with as little clothing as possible and empty pockets, without electronic devices.
- Remain still during the measurement. Extend your arms when measuring on a Tanita segmental body composition scale with hand electrodes.
- Keep the body composition scale in a cool and dry room, not in the bathroom due to humidity.
- Finally, keep your scale clean and free of dust.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Inaccurate or inconsistent readings | Scale not on a flat surface; feet not clean/dry; movement during measurement; recent food/drink/exercise. | Ensure scale is on a hard, flat floor. Stand barefoot with clean, dry feet. Remain still. Measure at a consistent time, ideally in the morning before eating or exercising. |
| Display shows "Error" or no reading | Poor contact with electrodes; low batteries; exceeding weight limit. | Ensure firm contact with both foot and hand electrodes. Replace batteries. Check weight limit (150 kg). |
| SD card data transfer issues | SD card not inserted correctly; card full or corrupted; incorrect file format. | Reinsert SD card. Check card capacity. Ensure card is formatted correctly (FAT32). Consult manual for specific data transfer steps. |
| Scale does not turn on | Dead or incorrectly installed batteries. | Check battery polarity. Replace all 4 AA batteries with new ones. |
